SAMUEL .o. MOORE, or BOSTON, MASSACHUSETTS Letters Patent No. 83,874,dated November 10, 1868.

IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters Patent and making part of thelame.

To all whom it may concern:

Be it known that 1, San Urn. O. Moons, of Boston, Suffolk county, Stateof Masszughusetts, have ir'rveuted certain new and useful improvementsin Lamps; and i do hereby declare the ibllowing description andaccompanying drawings are sufficient to enable any person skilled in theart or science to which it most nearly appertains, to make and use my,said invention or improvements without further invention 'or experiment.

'The naturgeof my invention and improvements consists in theConstruction and arrangement of a burner for kerosene-lamps, in themanner hereinafter described, and represented in the accompanyingdrawlllgS. I

1n the accompanying drawings- Figure 1 is an elevation of a lamp-topwith my improvements Figure 2 is a plan or top View of the same; and

Figure 3 isa side and end view of the traversing or outer tube,corrugated. In these drawings, A is the-serew-plate or izup, holding thewick-tube B, and fitted to screw into the top of the oil-cup or vessel,and provided with a horizontal shaft, U, with a finger-disk, l), andnotched disks, E 15,130 adjust the wick, as required:

1 make an external tube, F, and fit it to traverse on the outside of thewieletube B, so that it may be readily adjusted higher or lower on thewick-tube, and held by the friction of one tube against the other, or bysome convenient device. for that purpose.

The object and purpose of this tube F are to hold the perforated plateor cup G, which is fastened to it, to hold the blaze-cap H, which may bemade in the form shown, or in such other form as will answer thepurpose, so that by traversing the tube F, the blaze-cap B may be setnear to or far from the top ofthe'wiektube B, to adapt the cap to thesize of the blaze, to make the combination more perfect, and lessenthetendency to smoke. I

'lo-si-rpport' the chimney, with its lower end some distance below theedge ofthe blaze-cap, I fasten some wire hangers or loops, I I, to theedge of the cup or blaze-cap, or both, so that they hang down somedistance below the edge of the blaze cap and cup, and hold the lower endof the chimney, and support it altogether, if it has no other support;or, these hangers, or braces equivalent, may be fastened to thescrew-cup A, and extend upward, so to support the chimney at the properheight, above described.

The cl'limuey should be larger than the blaze-cap, so as to leavesu'fiicient space for the air to pass up between the edge of the cap orcup and the chimney, to supply air to the blaze above the cap,.and theblazecap and perforated cup may be placed a little apart, and beconnected by narrow strips, or by the chimney-supporters or hangers, sothat less heat may be communicated from the cap above to the cupbeneath. Also, the traversing-tube F may be made corrugated, asrepresented in fig. 3, and it will then allow the air to pass up betweenthe tubes, and thus keep them, particularly the outer one, much coolerthan they would otherwise be, and consequently less heat will becommunicated to the cup and cap .which they support. I

Having thus fully described my invention, What I claim, and desire tosecure by Letters Patent, is-

1. The combination and arrangement of the cap H, cup G, hangers I, slideF, and tube B,'all constructed and operating in the manner described.

'2. So arranging the chimney-supporters, that the lower edge of theehimney'shall extend below the level of the rim of the base-plate,substantially as described and shown.

' 3. The hangers or supporters 1, whether depending from the base-plateor rising from the screw-cup, when so arranged as to support the loweredge of the chimney below the rim of the base-plate, as and for thepurpose set forth.
